Description

Technical Field

[0001] The present invention relates to the technical field of loaders, and in particular to a skid steer loader with a bucket that is easy to dismantle and rotate. Background Art

[0002] Loaders are earthwork machines widely used in construction projects such as roads, railways, buildings, hydropower, ports, and mines. They are mainly used to shovel bulk materials such as soil, sand, lime, and coal, and can also do light shoveling of ore and hard soil. By replacing different auxiliary working devices, they can also do bulldozing, lifting, and loading and unloading of other materials such as wood.

[0003] In order to adapt to various construction environments, loaders are usually equipped with buckets of different specifications to adjust the volume of a single load. However, the existing connection method between the bucket and the loader mostly adopts the method of latch positioning. When the bucket needs to be installed or removed, it is usually necessary to manually use a hammer to knock the latch to disengage it from the pin groove, thereby separating the bucket from the loader drive arm. However, this method has the following disadvantages: First of all, this operation method is time-consuming and labor-intensive. Since the latch needs to be manually knocked, each installation or removal of the bucket requires a lot of time and physical strength, especially when the bucket is frequently replaced. This operation method is particularly inconvenient. Secondly, the latch is easily worn due to repeated hammering. Long-term use of the hammering method will damage the surface of the latch, affecting its service life and positioning accuracy. In addition, frequent knocking may cause the latch to deform, further affecting the connection stability between the bucket and the loader. In summary, the traditional latch positioning method has many inconveniences in practical applications. It not only increases the labor intensity of the operator, but also easily causes wear of equipment components, thereby affecting the overall performance and service life of the equipment. Therefore, the development of a more convenient, efficient and durable bucket installation and removal method is of great significance to improving the work efficiency of the loader and reducing maintenance costs.

[0004] Therefore, it is necessary to design a skid steer loader that is easy to dismantle and rotate the bucket. Summary of the invention

[0031] The following descriptions are merely preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention.

[0032] Embodiment 1: A skid steer loader that is easy to dismantle and rotate the bucket, such as Figure 1-Figure 5As shown, the loader 1 includes a shoveling mechanism 2, a first fixing mechanism 3 and a second fixing mechanism 4. The loader 1 is provided with a shoveling mechanism 2, which includes a driving arm 21, a shoveling assembly, a second fixing rod 232, a second mounting plate 24, an electric push rod, a connecting ring 26 and a docking tube 27. The loader 1 is rotatably connected with the driving arm 21, the shoveling assembly is symmetrically connected with the second fixing rod 232, the driving arm 21 is connected with the second mounting plate 24, the second mounting plate 24 is symmetrically installed with a first electric push rod 25 through a fixing member, and the telescopic ends of the first electric push rod 25 are connected with connecting rings 26. The first fixing ring 32 is connected to the telescopic rod of the first electric push rod 25, and the second electric push rod 31 is connected to the first fixing ring 32. The telescopic end of the second electric push rod 31 is hinged with a rotating plate 33, and the front end of the rotating plate 33 is hinged with a second fixing ring 34, and the second fixing ring 34 is connected to the docking tube 27.

[0033] like Figure 2-Figure 5 As shown, the shoveling assembly includes a latch 22, a first mounting plate 23 and a bucket 231. The driving arm 21 is rotatably connected to the first mounting plate 23, a slide groove is provided on the first mounting plate 23, docking holes are symmetrically provided on the upper part of the driving arm 21 and the first mounting plate 23, the latch 22 is inserted in the docking holes, the first mounting plate 23 is slidably connected to the bucket 231 up and down, the rear part of the bucket 231 is provided with four hole grooves, and the second fixing rod 232 is respectively connected to the left and right sides of the bucket 231.

[0034] like Figure 5-Figure 7 As shown, the second fixing mechanism 4 includes a first fixing rod 221, a third mounting plate 41, a double-axis motor 42 and a connecting tube 43. The ends of the latches 22 that are close to each other are connected with the first fixing rod 221. The upper part of the driving arm 21 is connected with the third mounting plate 41. The double-axis motor 42 is installed on the third mounting plate 41 by bolts. The output shafts of the double-axis motor 42 are connected with the connecting tube 43 by couplings. The connecting tube 43 is provided with an S-shaped slide groove 431. The first fixing rod 221 is located at Inside the corresponding S-shaped groove 431, the output shaft of the dual-axis motor 42 will drive the connecting tube 43 to rotate in the opposite direction, and the first fixing rod 221 will slide in the S-shaped groove 431 toward the position of the dual-axis motor 42, thereby driving the latch 22 to move closer to the dual-axis motor 42. When the first fixing rod 221 slides to the end of the S-shaped groove 431 closest to the dual-axis motor 42, it indicates that the latch 22 has been disengaged from the docking holes on the drive arm 21 and the first mounting plate 23, and the bucket 231 is no longer fixed.

[0035] like Figure 12-14 As shown, it also includes a clamping block 261, a first elastic member 262 and a limit block 6. The clamping block 261 is slidably connected inside the connecting ring 26, and the first elastic member 262 is connected to the connecting ring 26 through a spring seat; the connecting ring 26 is connected with a limit block 6, and the limit block 6 can be matched with the second fixed rod 232. The connecting ring 26 can fix the position of the second fixed rod 232 to prevent the second electric push rod 31 from malfunctioning during operation, and the docking tube 27 is directly separated from the second fixed rod 232, causing the bucket 231 to tilt or fall off, thereby preventing accidents in advance and ensuring construction safety; the limit block 6 contacts and fits with the second fixed rod 232. At this time, the center point of the docking tube 27 and the center point of the second fixed rod 232 are located on the same horizontal line to ensure the precise docking of the docking tube 27 and the second fixed rod 232, thereby avoiding wear caused by misalignment.

[0036] When the bucket 231 is to be replaced, the second electric push rod 31 is first started, and the telescopic rod of the second electric push rod 31 will move forward. During this process, the telescopic rod of the second electric push rod 31 will slide on the first fixing ring 32, prompting the rotating plate 33 to rotate. When the rotating plate 33 reaches its rotation limit, it will drive the second fixing ring 34 to move rightward, and the second fixing ring 34 will drive the docking tube 27 to move rightward together. During this process, the block 261 will be lifted up by the docking tube 27, and the first elastic member 262 will be compressed, so that the block 261 can be disengaged from the card slot of the docking tube 27 and no longer fix the docking tube 27. When the second fixing rod 232 is disconnected, it indicates that the docking tube 27 no longer fixes the bucket 231. Next, the dual-axis motor 42 is started, and the output shaft of the dual-axis motor 42 drives the connecting tube 43 to rotate in the opposite direction. At this time, the first fixing rod 221 slides in the S-shaped slide groove 431 toward the position of the dual-axis motor 42, thereby driving the latch 22 to move closer to the dual-axis motor 42. When the first fixing rod 221 slides to the end of the S-shaped slide groove 431 closest to the dual-axis motor 42, it indicates that the latch 22 has been disengaged from the docking holes on the drive arm 21 and the first mounting plate 23, and the bucket 231 is no longer fixed. At this time, the bucket 231 is not fixed to the device. Then, the loader 1 is operated to move the driving arm 21 to the rear of the bucket 231 to be replaced, and then the position of the bucket 231 is slightly adjusted manually so that the limit block 6 contacts and fits with the second fixing rod 232. At this time, the center point of the docking cylinder 27 and the center point of the second fixing rod 232 are located on the same horizontal line to ensure the accurate docking of the docking cylinder 27 and the second fixing rod 232, thereby avoiding wear caused by misalignment. When the docking cylinder 27 and the second fixing rod 232 are accurately docked, the latch 22 will also be aligned with the docking hole of the first mounting plate 23 on the bucket 231. At this time, the second electric push rod 31 is started again, and the second electric push rod 31 is turned on. The telescopic rod of the rod 31 will move backward, and the rotating plate 33 will be affected by the backward movement of the telescopic rod to move first to the left and then backward. During this process, the docking tube 27 will move to the left until the block 261 is aligned with the slot on the docking tube 27. At this time, the first elastic member 262 will make the block 261 rebound and reset, and re-fit with the slot on the docking tube 27, so as to fix the docking tube 27. The connecting ring 26 can fix the position of the second fixing rod 232 to prevent the docking tube 27 from directly separating from the second fixing rod 232 when the second electric push rod 31 fails during operation, causing the bucket 231 to tilt or fall off, thereby preventing accidents in advance and ensuring construction safety.The docking cylinder 27 will be plugged into the second fixing rod 232 and reset to the initial position, thereby fixing the left and right sides of the bucket 231. Then, the double-axis motor 42 is started again, and the output shaft of the double-axis motor 42 drives the two connecting cylinders 43 to rotate in opposite directions, so that the first fixing rod 221 slides in opposite directions along the S-shaped slide groove 431 of the connecting cylinder 43, so that the latch 22 docks with the driving arm 21 and the docking hole on the first mounting plate 23 of the bucket 231 to be replaced. After the docking is completed, the double-axis motor 42 is turned off to fix the middle part of the bucket 231. At this time, the replacement work of the bucket 231 is completed. Whether it is fixing the left and right sides or the middle part of the bucket 231, except that the worker needs to slightly adjust the position of the bucket 231, the other fixing steps are automated, which greatly improves the efficiency of replacing the bucket 231 and reduces the wear of the latch 22 and the docking hole. ;

[0037] Embodiment 2: Based on embodiment 1, Figure 8-Figure 11 As shown, it also includes a limiting mechanism 5, a limiting mechanism 5 is provided on the first mounting plate 23, and the limiting mechanism 5 includes a third fixing rod 51, a fourth mounting plate 52, a second elastic member 53 and a limiting rod 54. The third fixing rod 51 is symmetrically connected to the first mounting plate 23, and the fourth mounting plate 52 is slidably connected to the fixing rod. The second elastic member 53 is connected between the fourth mounting plate 52 and the third fixing rod 51 through a spring seat. Four limiting rods 54 are connected to the fourth mounting plate 52, and the limiting rods 54 are close to each other. The end of the bucket 231 is provided with an inclined surface, and the limiting rod 54 is inserted into the hole groove on the bucket 231, and the rear side surface of the bucket 231 contacts the inclined surface on the limiting rod 54. As the bucket 231 continues to slide down, the limiting rod 54 will be forced to move backward, and the fourth mounting plate 52 will also move backward, and the second elastic member 53 will be compressed. When the limiting rod 54 is aligned with the hole groove on the rear side surface of the bucket 231, the second elastic member 53 will push the fourth mounting plate 52 to reset, so that the limiting rod 54 fits with the hole groove, thereby fixing the bucket 231.

[0038] Another method for replacing bucket 231 is even simpler. First, the second electric push rod 31 is started to release the fixation of the left and right sides of bucket 231, and then the fourth mounting plate 52 is pulled backward. The fourth mounting plate 52 will drive the limit rod 54 to move backward together and make it disengage from the hole groove on bucket 231, thereby releasing the fixation of bucket 231. At this time, the second elastic member 53 will be compressed, and then the bucket 231 is fixed to the lifting device, and the lifting device is started to lift the bucket 231 upward. Since the bucket 231 and the first mounting plate 23 are slidably connected, the bucket 231 will rise on the first mounting plate 23 and eventually disengage from the first mounting plate 23. Then the fourth mounting plate 52 is released and the fourth mounting plate 52 will be reset. After that, the new bucket 231 to be replaced is hoisted to the front of the first mounting plate 23 and docked with the slide groove on the first mounting plate 23. Then the lifting device is started to make the bucket 231 move along the first mounting plate 23. When the stopper 54 is aligned with the hole groove on the rear side of the bucket 231, the second elastic member 53 will push the fourth mounting plate 52 to reset, so that the stopper 54 fits with the hole groove, thereby fixing the bucket 231. When the bottom of the bucket 231 touches the ground, the lifting device releases the fixation of the bucket 231. At this time, the second fixing rod 232 on the bucket 231 is horizontally aligned with the docking tube 27, and the second electric push rod 31 is started to fix it. In this way, the bucket 231 can be replaced by only releasing the fixation on the left and right sides of the bucket 231, and there is no need to release the fixation of the first mounting plate 23, which simplifies the steps, saves time, and makes the replacement of the bucket 231 faster.

[0039] During the construction process, if the angle of the bucket 231 needs to be changed, the first electric push rod 25 can be started. When the telescopic end of the first electric push rod 25 moves forward and backward, the bucket 231 will rotate around the pin 22 as the axis, thereby changing the angle of the bucket 231. When the telescopic rod of the first electric push rod 25 moves, the first fixing ring 32 will move with the second electric push rod 31 and the telescopic rod of the first electric push rod 25, so that the device can flexibly rotate or adjust the direction in the connected state while fixing the left and right sides of the bucket 231, which is convenient for rotation and will not hinder the normal use of the loader 1.

[0040] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. Therefore, all equivalent changes made to the contents described in the claims of the present invention should be included in the scope of the claims of the present invention.
